FURNACE WALL.

jApplication led April 27, 1925.

Our invention provides an improvement in furnace walls or walls adapted to stand high temperatures, and, more particularly, to that type of wall structure that comprises a permanent outer wall and a replaceable inner wall.. The invention is' directed chiefly to improved means for replaceably supporting blocks of the inner wall from the permanent or outer wall.

Generally stated, the invention consists of the novel devices and combinations ol devices hereinafter described and donned in the claims.

.ln the accompanying); drawings, which illustrate the invention, like characters indicate like parts throughout the several viewsa llteterring to the drawings:

lll'ip". l is an elevation show/ing a portion oit the improved wall structure, looking at the inner tace thereol" lllig. 2 is a vertical section taken approximately on the irregular line 2-2 oi' lling. 1, some parts being broken away;

litiga 3 is a perspective showing,l in detail one ot the metallic hanger brackets;

l'ipg. el is a perspective showingv in detail one oil' the bracket anchors; f

y llipg.. 5 is a detail in perspective showing one ot the base blocks oi the inner wall;

lig.. d is a perspective showingn in detail one oil the beltiorininp; blocks ot the inner wall;

ll'ipn l" is a detail in perspective showing one oi' the crown blocks of the inner wall; and

llig. 8 is a perspective showing' one ot the horizontal partition blocks or plates.

'lhe outer wall structure includes upright beams or buckstays 9, preferably hbeams or channel irons, vertically spaced horizontal beams 1U, preferably I-beams, and outer wall blocks or bricks 11 and 12. The beams 10 are bolted or otherwise rigidly secured to the buckstays 9 and, as shown, an outer sheet metal casing 13 is interposed between the said beains 9 and 10 to :torna a covering for the brickwork ll and 12. The bricks'or blocks 1l rnay be common bricks laid in any suitable way but, as shown, are laid as headers. The upper and lower bricks or blocks 12 are beveled to tit the channels of the I-beains 10.

For supportingr the blocks or tile inembers of the replaceable inner wall, we pro- Seral No. 26,274.

vide hanger brackets and cooperatinrv bracket anchors, both oi which are preferably of cast 1ron. The bracket anchors lll are preferably flanged for strength and are formed at their upper extremities with liooleacting lock flanges 15 and at their lower extremities with pockets 16. rl`hese anchors 14 are adapted to be hung; on the upturnedl inner flanges ot' the horizontal I-beams 10 and, as is obvious, they could be likewise hung on upturned Hanges ot channel beams. When thus hung'9 the bracket anchors will bear against the inner laces ot thc respective beams l0, as best shown in Fig. 2, by reference to which it will be noted that certain ot the blocks ll and 12 have been chipped away or removed to at- 'lord clearance lfor the flanged upper portions oi the anchors, and that the said blocks, locked in working' positions or against accidental removal.

VlFhe hanger brackets 17 are vlim-shaped in horizontal cross section, that is, they are provided with laterally projectingI retaining;

hangers 1li. 'll`he extreme upper portions ot' said brackets are extended obliqncly to the vertical body portions and are 'terminated in hook-acting lock llanges 19 that are adapted to be seated in the pockets 1G ol the respective anchors 1d., llt their lower portions, the brackets 17 are termed with horizontal shelves or bearing,r plates 2O and with outwardly projected stop webs 21 shown as termed with bearing1 flanges 22, which latter are arranged to bear directly against the inner tacos oi the horizontally aligned .lf-beams 10.

As best illustrated in liig, l, the replaceable inner wall is made up oi blocks or tiles laid in horizontal belts with the blocks of the adjacent belts staggered and, hence, the cooperating1 hanger brackets 1l" of the several belts will also be staggered. Each olf the said belts is, as shown, made up of base blocks 23, intermediate blocks 24 and crown blocks 25. rllhe base blocks 23 are formed with vertical T- shaped slots 26 that adapt them to be threaded or slid onto the retaining danges 18 oli the respective hanger brackets. These base blocks 23 rest directly on the shelves 20 of said brack cts. The intermediate blocks 241 are also formed with vertical T-shaped slots 27 that adapt them to be threaded or slid onto the said the anchors ara by Dil ' It should now be noted that the retaining flan es 18.l The crown blocks 25 are horizontal y slid into position on top of the upper la er of blocks 24 and, to clear the webs 21 of t e respective hanger brackets 17, they are formed with channels 28. b, base blocks 23 are provided with notches 29 and that the crown blocks 25 are provided with npstanding portions 30 that are overlapped with the notched portions of the adjacent base blocks 23,' so that they protect the metallic shelves 2O and the webs 21 of the hanger brackets 17. Also, it will be noted that there is clearance between the b1ocksv30 and the brackets and i bloc-ks 23, so that each belt is independently supported and capable of limited vertical movements to take care of uneven expansion and contraction of the metallic and non-metallic parts ofthe wall. By reference to Fig. 5,'it will be noted that the lower portions of the T-shaped slots 26 of the base blocks 23 are widened at 26'l so that the said blocks, which are quite deep can be freely moved horizon- `tally from wor ing positions when moved ver. tically on the guide flanfes 18 of the brackets 17 upward to points waere the narrow poi'- tions of the slots 26 are above said flanges 18. The horizontal partition blocks or plates 31 are laid -on the upper edges ofthe webs 21 of the brackets 17 and thus divide the space between the inner andouter walls into separated horizontal air channels A. The blocks or plates 31 are preferably made long enou h to span and restupon the Webs of two adjacent brackets.

With the arrangement described, the bracket anchors 14 are, as already indicated,

Apermanently hung on or applied to the cooperating beams 10. This permits the brackets 17, as well as the inner wall elements, to be reltel-locked with and `detachably placed from time to time without disturbing the outer wall.

What we claim is:

1. A wall structure comprising a relatively permanent outer wall and a replaceable inner wall, metallic members )ermanently incorporated in said outer wa l, metallic anchors raving hook-like portions interlocked to said permanently incorporated metallic members, hanger brackets having hook-like plortions inung from said anchors, said permanently incorporated metallic members' having ianges that interlock with the hook-like portions of said anchors, and said anchors having flanges that interlock with the hook-like portions of said hanger brackets, and blocks laid in belts and supported by said hanger brackets.

2. A wallstructure comprising a relatively permanent outer wall having horizontal flanged metal beams incorporated therein, metallic anchors having hook-like portions applied to the flanges of said beams and projeeting from said outer wall, and hanger brackets having hook-like u per endsldetachably interlocked to said ancliors, said rmanently incorporated metallic members aving flanges that interlock with the hook-like rtions of said anchors, and said anchors aving flanges that interlock with the hook-like portions of said hanger brackets, said brackets Aat their lower portions having shelves, and blocks laid in belts and supported on the shelves of said brackets and constituting a replaceable inner wall.

In testimony whereof we aiiix our signatures.
